RECORDING-LOCK.

Specification of Letters Patent.

Patented Feb. 2, 1915.

Application filed January 24, 1910. Serial No. 539,820.

To all whom it may concern Be it known that I, HARRY IV. BROWN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Recording-Locks,

of which the following is a specification.

The object of my invention is to provide an improved construction of recording lock in which the insertion of keys held by different persons will effect different contacts to estab ish connections for making records distinguished from each other; and further to provide for the momentary closing of a circuit embracing such contact devices and identifying recording means and other means such as time recording devices, such closing of the circuit resulting from the turning of the inserted key though not being directly caused thereby, the idea being to have the turning of the key set and trip circuit-closing means so that the key can not be manipulated either to prevent the closing of the circuit or to hold the same closed. In addition to such features as above indicated I provide means for throwing the bolt of the look from the inside and making a contact by insertion of the key for such purpose which contact provides for a differ ent connection than that established by insertion of any of the outside keys. Further I provide for the closing of the circuit by a watchmans key inserted from the outside and turned without throwing the bolt.

With the above stated and incidental objects in view the invention consists in certain novel features of construction and combinations of parts the essential elements whereof are recited in the appended claims and a preferred form of embodiment of which is described in detail hereinafter and fully illustrated in the drawings which accompany and form part of this specification.

Of said drawings Figure 1 represents the complete look as applied to the door or other closure the mechanism being shown in elevation with the inclosing casing for the most part in section, full lines illustrating the normal condition of certain movable parts whereas dotted lines show an intermediate condition thereof brought about through partial turning of an inserted key; Fig. 2 shows some of the parts of Fig. 1 in similar elevation but differently positioned as when the circuit is momentarily closed; Fig. 3 is a section taken substantially on the line 3-3 of Fig. 1; Fig. 4 is a section taken substantially on the line -tl of Fig. 3; Fig. 5 shows certain of the parts in perspective and detached; Fig. 6 is a section taken substantially on the line 66 of Fig. 1; Fig. 7 is a section taken substantially on the line 77 of Fig. 1; Fig. 8 is a section taken substantially on the line 88 of Fig. l; and Figs. 9, l0 and 11 show the different keys for the lock.

The reference letter A designates the base plate of the lock and A the front plate through which the bolt B works, said bolt having a shank B sliding on the base plate A along a rib a formed thereon and having shoulders alternately engaged by a latch C pivoted to the bolt and yieldingly held to a central position by a fiat spring C, Fig. l,

said latch serving to hold the bolt against movement from either of its extreme positions otherwise than by the turning of a key. To the base plate A there is secured by screws (1 Fig. 6, the body D of an ordinary key structure such as the Yale in which body is journaled the barrel D. In the construction here shown this barrel is bifurcated at the inner end and there is slidingly engaged with the bifurcated portion a plunger E square in cross section and confined against removal from the barrel by a cap D secured over the inner end of the barrel and formed with a square opening through which said plunger slides, the latter having a foot 6 extending under the cap. This plunger E extends through a short tubular shaft or sleeve F journaled at one end in the base plate A and at the other in a frame plate A said sleeve being internally grooved to receive the corners of the plunger and maintain an engagement with the latter which will cause it to always rotate therewith while at the same time thephmger may slide through the sleeve. The latter carries a crank arm F, Fig. 4c, lying against the base plate A and adapted to work under the bolt and having a roller stud f to operate against transverse shoulders of the bolt and throw the same back and forth, said roller or the end of the crank arm also acting against the latch C to disengage the same from the shoulders of the rib a. A set of keys of different lengths but of corre sponding formation as to bits are adapted Lin to be inserted in the barrel D the slot of which leads to the outer end of the plunger E so that the key when inserted strikes against the foot 6 of the plunger and forces it in to a greater or less degree according to the length of the key.

Fig. 9 illustrates the key of the well known Yale kind which is adapted to be used in the manner above described and the dotted lines in this figure denote the different lengths of the keys.

It is obvious that the turning of any fully inserted key rotates the barrel D and the differentially movable plunger E, which latter, Whatever its longitudinal position, serves as an actuator for turning the sleeve F and crank arm F to throw the bolt from locked to unlocked position, or vice versa.

The inner end of the differentially movable actuator E bears against a pivoted arm G, and forms a positioning element for shifting such arm to one or the other of its various positions through its difierential movement as determined by the particular key employed, the free end of such arm constituting an electric contact device or movable electrode. This arm is pivoted to the fixed frame work, as shown at g, and has applied to it a spring g impelling it toward the base plate A and thus pushing the plunger E outward to the position shown in full lines in Fig. 6. The free end of this arm which is somewhat broadened for contact purposes, is adapted to move along a series of contact terminals h secured in a standard H of insulating material secured to the base plate A by a suitable bracket H. Wires it run from the respective terminal contacts 71. to b ndingposts H respectively, see Fi g. 1, wh ch b'nding posts may be wired to any suitable form of electric recording mechanism whereby imprints of different characters or other records will be made to show what particular key was used when the lock was operated. Normally the free end of the arm G lies against the base plate A out of contact with any of the terminals h. I have hee shown four terminals for the keys carried by different persons who are to enter and leave by the door to which this recording lock is applied, these being the rear four terminals.

In Fig. 6 the dotted lines illustrate the effect of introducing the longest one of the four keys, the arm being represented as moved back to the farthest point where it would contact with the rearmost terminal. The shortest of these keys would move the arm to contact with the second terminal and the keys of intermediate lengths would move the arm to engagement with the third and fourth terminals respectively. The first terminal is provided for making a connection by the introduction of an inside key such as shown in Fig. 10 so that when the door is locked or unlocked from the inside this will be recorded as distinguished from the records of locking or unlocking from the outside. This inside key does not operate through the same device as do the outside keys in throwing the bolt. A separate sleeve or barrel I is journaled in the base plate A and frame plate A Figs. 1, 8 and 4, such sleeve or barrel carrying a crank arm I just like the crank arm F and having a similar roller stud 2' to act against the shoulder of the bolt and against the latch C. This key barrel or sleeve I is slotted along one side to accommodate the fin or elongated bit 2' of the key 1 Fig. 10, so that the barrel or sleeve will be rotated by the key. There is an enlargement at the inner end of the slot and into that enlargement normally proj ects a lug j on one arm of a bell crank lever J which is pivoted to the frame plate A and pressed by a spring j in a direction to thrust the lug into said enlargement as illustrated in Fig. 1. The key I is beveled on one side as shown at i in Fig. 10, the bevel extending across the end of the tin or bit 77 and adapted when the key is inserted to act against the lug j and rock the bell crank lever J against the stress of the spring j. The long arm of said bell crank lever has a beveled lug f, Fig. 5, which extends under the movable contact arm G and is adapted upon the rocking of the lever to engage a beveled lug on said arm to move the latter into engagement with the; first of the series of terminal contacts h and thus make the desired connection to record the operation of the lock from the inside.

Passing now to the means for momentarily closing the circuit through such contact devices or otherwise, there is journaled upon a post or arbor is projecting from the base plate A, a cylindrical metal block K cut away on one side as illustrated at it and there is secured to a strip or bar of insulation K on the base plate A a spring contact strip 1' whose free end normally stands in the cut away part In without contact with the block K. The latter has applied to it a spiral spring 75 Fig. 4, whereby it is normally held in the position illustrated in Figs. 1 and 4, a pin 70 carried by it contacting with a lug 70 on the base plate as illustrated in Fig. 4. It is obvious that a partial rotation of said cylindrical block will bring its periphery into contact with the strip K and furthermore that release of the block will cause its spring to break the contact. Now said block has secured to it a cam-shaped disk K with an abrupt ra dial shoulder 70 adapted to be acted upon by a wiper pawl M for the purpose of momentarily clos ng the circuit in the manner just mentioned. This wiper pawl is pivoted on the end of a curved arm or lever M pivoted at its inner end to the frame plate A as shown at m and normally held back by a spring M which is connected at one end to said frame plate and at the other end to the wiper pawl M so that the spring not only serves to retract the curved arm or lever but also holds said wiper pawl against a pm at on the lever as illustrated 1n F 1g. 1. The normal position of the wiper pawl as %here shown is behind the cam disk K*. The rocking of the lever M against the stress of the spring h 2 will cause the curved edge of this wiper pawl to contact with and wipe over the curved edge of the cam disk in rear of the radial shoulder it the wiper pawl rocking on this pivot against the stress of said spring M to the position indicated by dotted lines in Fig. 1 which shows the point of the wiper pawl just about to pass the point of the cam disk. As soon as these points have passed each other then the wiper pawl snaps in front of the radial shoulder 733 and on the return of the lever M acts against said shoulder turning the cylindrical block K against the stress of its spring If to the position shown in Fig. 2 where the point of the wiper pawl is about to again escape the point of the cam disk moving in the opposite direction. Immediately upon such escape the cam contact block K is returned to normal by its spring. It will therefore be obvious that in order to effect a momentary contact in closing the circuit it is only necessary that the key when turned shall retract the lever M and release the same. As to keys thus far referred to, this effect is produced through the medium of the bolt, which being thrown by the key in one direction or the other first sets or retracts the lever M to position to cause the operation of the circuit-closing block K, and then trips or releases said lever before the bolt reaches its extreme of movement. Thus the bolt carries a pivoted wiper pawl or flipper N having a tail piece a working between studs 02 on the bolt. The tapered end of this wiper pawl or flipper is adapted to act upon a pin or stud m on a branch of the lever M. Normally with the bolt retracted this flipper stands away from said stud or pin as illustrated in Fig. 1, full lines. lVhen the bolt is moved outward the flipper advances and contacts with said stud or pin its tail being thrown against the forward stud a and by wiping over said pin retracts the lever M. Before the bolt reaches the end of its movement the flipper N escapes past the stud or pin m whereupon the lever M springs back and as its wiper pawl M has been carried in front of the shoulder 10 it will operate to turn the contact block K and then release the same. When the bolt is d awn back exactly the same effect is produced. the other inclined face of the flipper N acting against he Stud 01' pin m The night watchmans key P, Fig. 11, is

inserted in a third barrel or sleeve 1 journaled in the base plate A and the frame plate A and this sleeve is slotted similarly to the inside key sleeve or barrel I and the key P has an elongated bit or fin 79 similar to that on the key I though it does not perform a similar function as to any setting of the contact arm G. The latter is not affected by insertion or turning of the night watchmans key. The bit of the night watchmans key by engaging the slot of the barrel is enabled to turn the latter and this barrel carries a cam P of the snail back variety which cam is adapted to act upon a pin or stud 7'1 projecting from the lever M through a slot in the frame plate A Turning of the night watchmans key by rotating this cam serves to set and trip said lever M and thus effect the oscillation of the contact block K in the same manner as the turning of the keys heretofore described. Thus the cam first retracts the lever until its wiper pawl M passes the point of the disk K and then releases said lever with the same effect as already described.

In order to compel the full operation of any key to project the bolt or retract the same I provide a locking arm Q, pivoted to the frame plate A at g and connected by a spring 9 with the lever M, said arm having a curved finger g lying against said lever. The rear end of the arm is formed with a square lug g which is adapted to coiiperate with the rear stud a on the bolt which stud is elonagted for the purpose. Normally this lug stands off from the line of travel of said stud as shown in Fig. 1 but as a key is turned to move the bolt and the lever M is at the same time advanced, the pin it having moved in front of the lug 9*, the spring will be put under tension and as soon the bolt moves far enough to carry its pin or stud n beyond the square lug the latter will snap over said pin thereby locking the bolt against reverse movement. lVhen the bolt is moved from a retracted to a locking position the side of the lug toward its pivot will thus engage the pin n to lock the bolt, and when the bolt is thrown back or withdrawn the other side of the lug will come into engagement with said pin. However, at the eX- treme of either movement of the bolt the lever M is of course restored and acting against the curved finger g of the locking arm Q will disengage the later from tie stud n of the bolt or move it out of the path of the latter. Turning of the barrel 1 otherwise than by the key I is prevented by the engagement of the lug j in the slot of the barrel, and turning of the barrel P otherwise than by key P is similarly prevented by the engagement of a lag 79, on a springactuated bell-crank lever P with the slot placed by the beveled end of the fin p in' said key P.

It will now be seen that the above described devices are well calculated to thoroughly fulfil the objects primarily stated, yet it is to be understood that the constructions here shown are susceptible of modification within the scope of the invention.
